Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. Sublimation is an endothermic process that occurs at temperatures and pressures below a substance's triple point in its phase diagram, which corresponds to the lowest pressure at which the substance can exist as a liquid. The reverse process of sublimation is deposition or … WebJul 30, 2024 · Problem. Given: The heat of fusion of ice is 333 J/g (meaning 333 J is absorbed when 1 gram of ice melts).
